For Demons, not all light is useful to them; besides Sunlight, light emitted in various ways such as Firelight, lamplight, and electric light has no effect on Demons.
Because the essence of what they fear is not light, but a special energy that comes from stars.
So when they first saw the four beams of light shine down, even though the four Upper Rank Demons felt they couldn't dodge, they didn't feel any danger.
After all, it was still an hour before the Sun rose, and as long as it wasn't the Sun's light, it couldn't cause them any harm.
However, what they didn't know was that the four beams of light released by Adam were his light magic used in conjunction with the Eternal Flame's energy; their essence was Sunlight, and their intensity was not the same as when the Sun shines on the Earth's surface.
It was roughly the intensity of Sunlight at the Sun's surface; being hit by it was equivalent to being directly thrown into the Sun.
What is the Eternal Flame? It is the source of power for the Fire Giant Surtur, created by fusing the energy of a thousand stars, which is equivalent to the power of a thousand Suns.
Adam, having absorbed the Eternal Flame, could naturally transform and manifest power with the same attributes as the Eternal Flame.
Therefore, by combining it with the method of releasing light magic, he could easily release high-intensity Sunlight.
In fact, if he wanted to, it wouldn't be impossible to directly create a star; it's just that the Earth wouldn't be able to withstand it and would be directly incinerated.
Thus, the result was obvious: within less than two seconds of being enveloped by the four light pillars, the four Upper Ranks turned into air and completely vanished.
"Hiss!"
Seeing the four Upper Rank Demons instantly annihilated by Adam, and in such a manner, everyone's eyes widened, and Kibutsuji Muzan gasped, saying nothing and immediately fleeing the scene at his fastest speed.
As he fled, he muttered in fear:
"How can such a person exist? How can someone release Sunlight personally? Why? Why appear when I am about to fulfill my wish? Damn it, damn it, damn it!"
This time, the fear in his heart was even greater than when he faced Yorichi Tsugikuni years ago.
Because he knew that if his body was touched by any one of those four light pillars, he would suffer the same fate, no different from his subordinates; even splitting into pieces of flesh to escape would be impossible.
"He just ran away?"
Seeing Kibutsuji Muzan flee so decisively, the Sound Pillar couldn't help but feel a little incredulous.
Kibutsuji Muzan, the progenitor of Demons, whom their Demon Slayer Corps had fought against for so many years, was actually so terrified when facing Adam.
"So it's called Transparent World."
At this moment, Adam had also finished reading Kokushibo's memories and knew that Tanjiro's state just now had been achieved by Yorichi Tsugikuni long ago, who had also given it a name.
A flash of Sunlight passed through his hand, and Kokushibo also followed the fate of the other Upper Ranks.
"With this, Ultra Instinct should be no problem."
Kokushibo had studied the Transparent World state for several centuries, making it far more complete than Tanjiro's newly comprehended version.
Having obtained Kokushibo's memories, Adam would basically be able to fully master it after spending some time back home.
"Mr. Adam. Kibutsuji Muzan… fled."
Seeing Adam kill Kokushibo and come back to his senses, the Sound Pillar cautiously reminded him.
Adam smiled:
"He can't escape."
The entire Planet was within the range of his mental coverage; unless Kibutsuji Muzan left this Planet, Adam could find Kibutsuji Muzan with a mental scan.
Moreover, he had previously left a Flying Thunder God Mark on Kibutsuji Muzan.
His figure flashed, and when he reappeared, he already held a person in his hand—it was Kibutsuji Muzan.
"What?!"
Kibutsuji Muzan was utterly bewildered at this moment; he had already fled far away, so how could he be back here?
"Black Blood Thorns!"
Although he didn't know why he had returned here and fallen into Adam's hands, he decided to strike first and immediately unleashed one of his strongest Blood Demon Arts.
His body's blood transformed into thorns, piercing towards Adam's physical body with unparalleled speed.
Unfortunately, Adam merely glared, and those blood thorns, which could easily penetrate even Upper Ranks, were all reflected back onto his own body.
"Seal!"
He reached out and patted Kibutsuji Muzan's head; dense arrays of techniques immediately enveloped Kibutsuji Muzan from head to toe, then disappeared into his body.
"You… what did you do to me?"
Kibutsuji Muzan's eyes were filled with terror.
Because he found that he could do nothing now except speak; his physical body couldn't move, and he couldn't even use Blood Demon Arts, as if he had turned into a piece of wood.
"I'll leave him for you to deal with. My time is almost up, so I'm leaving."
After sealing Kibutsuji Muzan, Adam casually threw him at the Sound Pillar's feet, as if he were throwing away trash.
Since his goal had been achieved, there was no need to keep Kibutsuji Muzan to temper Tanjiro anymore.
"Mr. Adam."
Looking at the motionless Kibutsuji Muzan at his feet, the Sound Pillar didn't know what to say for a moment.
"Oh, right, Tanjiro, I saved your family."
Adam, who was about to end the Dream Walking Technique, suddenly remembered something, waved his hand to open the Primordial Space, and released Tanjiro's mother, younger brother, and younger sisters whom he had revived earlier.
"Mother, Takeo, Hanako, Shigeru, Rokuta!"
Tanjiro and Nezuko couldn't believe their eyes; they were actually seeing their deceased relatives again.
After a tearful reunion, Tanjiro quickly thanked him:
"Mr. Adam, thank you…"
But at that moment, he realized with a shock that Adam had already vanished into thin air.
On the other side, Adam, who had returned to the Marvel Universe, resumed his peaceful life, except that among his many Training projects, there was now the Training of the Transparent World.
He did not immediately go to the Dragon Ball World to learn Ultra Instinct from the Angels, even after mastering the Transparent World.
Ultra Instinct was certainly something to learn, but only after he could transform into Super Saiyan 4; otherwise, if things didn't go smoothly, he would need sufficient self-preservation capabilities.
Time flew by; Wanda was nine months pregnant and would give birth in another month.
And during this period, Adam discovered something very important to him.
That was, the Justice Value progress bar on his panel was gone!
What did this mean? It meant that he would no longer gain Justice Value for doing good deeds, would not unlock new protagonist templates, and no new Worlds would appear.
Fortunately, the previous protagonist templates could still be used as usual.
But this also made Adam wary; since the Justice Value progress bar could disappear, did that mean the panel itself might disappear one day?
He might never be able to load these protagonist templates or enter those Worlds again.
If that were truly the case, then he would need to speed up his progress.
